    HI,

    I'm in the process of upgrading my bathroom lights to those Sfx IP44 fixed downlights. Do I need heat resistant cable to conect from the existing junction box to each transformer. (I'm using one transf. per light). I am putting in 2 x 50W 12v lights in place of one light. (A total of 4 lights in the ceiling).

    thanks in advance.

    I dont see why you need heat-resistant cable, or indeed why you thought you needed it.

    Second, why are you using one transformer per light? This is very energy-inefficient and frankly, pointless.

    Its a good idea to fit heat resisting cable from the transformer to the light fitting. Don't forget, you'll need to fit a firecap to each of your fittings to comply with fire/building regs. This means that the cable will run through the fire hood to the connection box on the top of the fittng and these things run HOT.

    No need to use heat resisting cable from the J/B to the mains side of the transformer though.

    Au contraire, mon brave, it's the best way to do it.
